NAME
       URI::Encode - Simple percent Encoding/Decoding

SYNOPSIS
           # OOP Interface
           use URI::Encode;
           my $uri     = URI::Encode->new( { encode_reserved => 0 } );
           my $encoded = $uri->encode($data);
           my $decoded = $uri->decode($encoded);

           # Functional
           use URI::Encode qw(uri_encode uri_decode);
           my $encoded = uri_encode($data);
           my $decoded = uri_decode($encoded);

DESCRIPTION
       This modules provides simple URI (Percent) encoding/decoding

       The main purpose of this module (at least for me) was to provide an easy method to encode
       strings (mainly URLs) into a format which can be pasted into a plain text emails, and that
       those links are 'click-able' by the person reading that email. This can be accomplished by
       NOT encoding the reserved characters.

       This module can also be useful when using HTTP::Tiny to ensure the URLs are properly
       escaped.

       If you are looking for speed and want to encode reserved characters, use URI::Escape::XS

       See this script <https://github.com/mithun/perl-uri-
       encode/raw/master/.author/benchmark.pl> for a comparison on encoding results and
       performance.

METHODS
   new()
       Creates a new object, no arguments are required

               my $encoder = URI::Encode->new(\%options);

       The following options can be passed to the constructor

       encode_reserved
                   my $encoder = URI::Encode->new({encode_reserved => 0});

           If true, "Reserved Characters" are also encoded. Defaults to false.

       double_encode
                   my $encoder = URI::Encode->new({double_encode => 1});

           If false, characters that are already percent-encoded will not be encoded again.
           Defaults to true.

               my $encoder = URI::Encode->new({double_encode => 0});
               print $encoder->encode('http://perl.com/foo%20bar'); # prints http://perl.com/foo%20bar

   "encode($url, \%options)"
       This method encodes the URL provided. The $url provided is first converted into UTF-8
       before percent encoding. Options set in the constructor, or defaults, can be overrided by
       passing them as the (optional) second argument. Options passed must be a hashref.

           $uri->encode("http://perl.com/foo bar");
           $uri->encode( "http://perl.com/foo bar", { encode_reserved => 1 } );

   "decode($url)"
       This method decodes a 'percent' encoded URL. If you had encoded the URL using this module
       (or any other method), chances are that the URL was converted to UTF-8 before 'percent'
       encoding. Be sure to check the format and convert back if required.

               $uri->decode("http%3A%2F%2Fperl.com%2Ffoo%20bar");

EXPORTED FUNCTIONS
       The following functions are exported upon request. This provides a non-OOP interface

       "uri_encode($url, \%options)"
       "uri_decode($url)"

CHARACTER CLASSES
   Reserved Characters
       The following characters are considered as reserved (RFC 3986
       <http://tools.ietf.org/html/rfc3986>). They will be encoded only if requested.

                ! * ' ( ) ; : @ & = + $ , / ? # [ ]

   Unreserved Characters
       The following characters are considered as Unreserved. They will not be encoded

               a-z
               A-Z
               0-9
               - _ . ~
